My invention relates, to improvements in means for connecting thesections of sectional boilers. In this type of boiler, each section isusually provided with a communicating opening in the steam dome and withsimilar openings in its water legs. The sections are so positionedthattheseopenings are adjacent one another and connecting nipples areusually provided, connecting these openings. In the type of boiler shownin my co=pending application, filed October 31, 1928, Serial Number11,543, it is somewhat difiieult to provide threaded nip les forconnecting the sections together,due to the fact that in this particulartype of boiler, thesections are formed of sheet steel and as the resultthese walls are comparatively thin, so that from a commercial standpointat least it is impossible to provide screw threads for the reception ofthe nipplesin the walls of the openings. My invention particularlydesigned for use in connection with the above type sectional boilers andis designed to'pr'ovide means whereby the sections of the'boiler g thesame together, a washer is slipped through the opening and the bolts 10insertmay be readily and easily assembled andconnecte'd. For the purposeof disclosing m invention, I have illustrated one embodiment thereof inthe accompan in drawings, in which: r

Each of the adja'cent openings 3and 1 is preferably circular in form andthe end section is also.provided with bolt receiving openings 5, which There are preferablyfourof these bolt openings,-5 arranged as indicated, Between the adjacentsections and surrounding theopenings are placed suitable, gaskets 7 andthe sections are clamped together by means of clamping washers8+8bearing against the inner face of the sections. These washers haveflattenedportionsf) atdiametrically op"- posite points tlereof so that,in assembling, the washers may be inserted through thecirculationopenings from the exterior of the section, the bolt receivingopenings merging with the circulation openings and the flat I portionsofthe washers permitting such insertions The washers are adapted to. bedrawn up by suitable bolts 10 having heads on one end andadapted toreceive threaded nuts 11 on the opposite end. v

In assembling the sections and connecting ed in the bolt receivingopenings in the washer and projected through the openings 5. The gasket7 is then hung on the bolts and the nezit adjacent section moved up, sothat the bolts project through-its bolt openings. A second washer maynow be placed in peeition, being inserted throu "h the eppesite epeningin the secticn. an slipped enth belts, after whieh the nuts 11 may bescrewed up drawing the eectiens ti t to eth r; In

I have found that the use of the cotter pins heretofore described andthe bolts slipped through. After the bolts and washers have beenpositioned a gasket of the type illustrated in Fig. 4- is mounted on thebolts on the exterior of the erected section. The .next section is thenplaced in position adjacent to the erected. section and, working throughthe circulation openings of this section, the second'washer and securingnuts are placed in position. I have found that frequently frictionexerted by the walls in the openings of the gasket prevents the boltsfrom slipping out of position during the positioning of the nextsucceeding section and the securing of the nuts in position. v I claimas my invention: r 1. A. sectional boiler comprising a' plurality ofsections, each section having a circulation opening therein, theopenings-of the adjacent sections being adapted to coincide,

means forv connecting said sections together comprising clamping.washers, arranged on the opposite faces of said sections and surroundingsaid openings, clamping bolts extending through said washers andsections, and a gasket between said sections and surrounding saidopenings.

2. A sectional boiler comprising a plurality of sections, each sectionhaving a circulation opening therein and bolt openings surrounding thesame and intersecting said circulation open1ngs, and means forconnectingsaid sections together, comprising clamping washers, arrangedon the opposite faces of said section, clamping bolts extending throughsaid washers and through said bolt openings in said sections, and agasket between said sections and surrounding said circulation openings.

3. A sectional boiler comprising a plurality of sections, each sectionhaving a circulation opening therein and bolt openings therethroughintersecting. said circulation openings, the openings of the adjacentsection coinciding, means for connecting said sections togethercomprising clamping Washers arranged on the opposite faces of saidsections, said washers having flattened edges at diametrically oppositepoints, clamping bolts extending through said washers and clamp saidparts together. said bolt openings in the sections, and agas ket betweensaid sections and surrounding said circulation openings.

4. A sectional boiler comprising a plurality of sections, each sectionhaving a circulation opening therein, the openings of the adjacentsections being adapted to coincide and means for connecting saidsections together, comprising clamping washers arranged on the oppositefaces of said sections, clamping bolts extending through said washershaving pin receiving eyes intermediate of their ends, and a gasketbetween said sections surrounding said openings.

5. A sectional boiler comprising a plurality of sections, each sectionhaving a circulation opening therein, and-bolt openings surrounding saidcirculation openings and intersecting the same, the openings of theadjacent sections being adapted to coincide and means for connectingsaid sections together, comprising clamping washers, having theiredgesflattened at diametrically opposite'points, arranged on the oppositeface of said sections, clamping bolts extending through said washers,securing pins passing through said boltopenings intermediate of theirends, and a gasket between said sections and surrounding saidcirculation open ings.

6. A sectional boiler comprising a plurality' of sections each having acirculation opening'therein and having bolt openings surrounding saidopenings and intersecting the same, a clamping washer having its edgesflattened sat diametrically opposite points, bolts passing through saidwashers and bolt openings for clamping said Washers and sectionstogether, and pins transversely passing through said bolts tom'aintainthe same in assembled position.

7. Asectional steel boiler comprising a plurality of sections eachhaving a circulation opening therein and having bolt openingssurrounding said'circulation openings and intersecting the same, aclamping washer having its edges flattened at diametrically oppositepoints to permit the passage of said washer through said circulationopenings and bolts extending through the Washers of adjacent sectionsfor clamping said washers and sections together.

8. A sectional steel boilerhaving circulation openings therein andhaving bolt openings surrounding said circulation openings andintersecting the same, a clamping washer having its edges flattened atdiametrically opposite points to permit the same to pass through saidcirculation openings, a gas ket interposed between the sections of theboilers and having bolt receiving openings therein and clamping boltspassed through the washers of the adjacent sections and through the boltopenings of the gasket to sectional boiler comprising a plurality ofsections each having a circulation opening therein and having boltopenings surrounding said circulation openings and.
